To aZZ whom t may concern.'

Be it known that l, JOHN DRIsooLL, a citizen of the United States, and a resident of Gypsum, in the county of Saline and State of Kansas, have invented a new and Improved Car-Coupling, of which the following is a full, clear, and exact description.

My invention relates to car couplers, and has for its object the provision of a simple, strong and efficient coupler which will couple automatically and which can be easily and quickly uncoupled from the exterior of the car provided with the coupler by applying pressure to the coupler at a proper place provided therefor.

With the above and other objects in view, the nature of which will more fully appear as the description proceeds, the invention consists in the novel construction, combination and arrangement of parts as herein fully described, illustrated and claimed.

In the accompanying drawings, forming part of the application, similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a plan view of my coupler, partly in section, to show the details of construction; F ig. 2 is a section on line 2 2, Fig. 1; Fig. 3 is a View similar to Fig. 1, the dotted line showing the coupler while the draw-bar is uncoupled; Fig. 1 is a side elevation of the draw-bar; and Fig. 5 is a cross section on line 5 5, Fig. 3.

Referring to the drawings, 6 represents a draw-head which has an end slot 7 for a draw-bar 8, which draw-bar has an opening 8. Pivotally mounted within the head and extending across the slot 7 is a coupling bar 9 which is maintained in normal position by a resilient member 10 located within a bore 11 in the head 6. The axis of the resilient member 10 is in alinement with a pivot 12 of the coupling-bar 9, consequently, the resilient member 10 will bring the coupling bar 9 into normal position no matter which way it is swung. Slots 13 are provided on each side 0f the bore 11 to permit the coupling bar to swing in either direction.

Mounted pivotally within the head 6 is a latch 14, the pivotal axis of the push bar being at right angles to the pivot of the coupling-bar 9. One end of the latch engages the coupling bar within the outer slot 13 (see Fig. 2), so that when a pull is exerted on the coupling bar the same will abut against the latch 14 and prevent the disengagement of the draw-bar from the coupling bar, thereby coupling the draw-bar to the drawhead. The other end of the latch 14C is engaged by a coil spring 15, which maintains the engagement of the latch with the coupling bar 9.

The endof the latch engaged by the spring is provided with a push-button 16 projecting above the draw-head 6, whereby pressure may be applied to the latch and the end engaging the coupling-bar may be forced out of engagement therewith, thereby permitting the coupling-bar 9 to move into the outer slot 13 when pull is exerted on the end of the coupling-bar located within the slot 7 of the head, thereby uncoupling the draw-bar from the draw-head. The coupling of the draw-bar with the draw-head is automatic, as the movement of either the draw-bar or draw-head toward one another will cause the end of the coupling-bar 9 within the slot 7, when coming into engagement with the draw-bar 8, to swing, as indicated in dotted line in Fig. 1, until the drawbar 8 clears the said end of the coupling bar, which, under the action of the coil spring 10, will automatically swing to its normal position to prevent a separation of the drawhead from the draw-bar, thereby coupling the two.

To uncouple the draw-bar from the drawhead, pressure is applied to the button 16, whereby the latch 14k will be displaced, as indicated in dotted line in Fig. 2, permitting the coupling-bar 9 to swing when pull is exerted on the end of the draw-bar within the slot 7, as indicated in dotted lines in Fig. 8.

1 claim:

ln a car coupling, the combination of a draw head having an end slot, a draw-bar having an opening adapted to engage said slot, a coupling bar pivotally mounted between its ends within said head and having one end thereof engaging the slot in the head, a Ocompression spring resisting the movement of said coupling bar on its pivot whereby the end of the coupling bar is maintained within the slot, a pivotally-mounted latch within the head, a compression spring for forcing said latch into engagement with the end of the coupling bar not engaged in the end slot of the head whereby the couplng bar is normally prevented from movename to this speceaton in the presence of ment on lts plvot when a pull 1s exerted on two subserlblng Wltnesses.

the coupling-bar, and a push-button asso-V eated With the latch whereby the same can JOHN DRISCOLL' 5 be forced to dsengage the coupling bar,s11b Witnesses:
